A woman who can't remember her past encounters a mysterious stranger in a chilling novel of mounting psychological suspense by the authors of The Last Girl Left.

She wakes on the shore of a remote lake in the middle of the night, freezing and afraid. With no memory of who she is or how she got there, she stumbles frantically toward the lights of a house. The handsome stranger who lives there is shocked to see a woman on his doorstep and takes her in.

Trapped by a winter storm and cut off from the outside world, she starts to suspect that all is not right with the house on Gravewater Lake-or the man, who says his name is Gregg. Because there are whispers in the night, and phantom footsteps pace the halls. Is Gregg hiding a dark secret, or is she losing her mind?

As she struggles to remember her past and make sense of her present, she soon discovers that people are not always who they seem, and the truth might be more deadly than she could ever have imagined.
